Title: Semiconductor device
Inventor: MATSUNAGA HITONORI
IPC: H01L23/52
Filed: 1989-11-20
Abstract: PURPOSE:To improve reliability by extending and enlarging a surface protecting film cut-out part for a bonding pad of a semiconductor chip to the surface region, which is lowered at a step part, of a lead take-out part aluminum layer connected to the bonding pad. CONSTITUTION:A surface protecting film cut-out part 4a is a cut-out part of a surface protecting film, on a bonding pad aluminum layer 2a and a lead take-out part aluminum layer 2b connected to the aluminum layer 2a, extended to the region lowered at a step part thereof formed by etching and removing that part leaving the part superposed on the peripheral part of the aluminum layer 2a and 2b. Accordingly, a ball of a wire 5 does not reach a surface protecting layer 3 on the lead take-out part aluminum layer 2b. Therefore, the external force from the ball is absorbed by only the aluminum layer 2b sliding outwardly and the shear stress produced in a lower insulating film layer 1 is reduced so that the deterioration of the insulating layer 1 can be prevented. Thus, the performance deterioration of the semiconductor element can be reduced and the reliability thereof can be improved.

Filed: 1988-11-29
Abstract: PURPOSE:To reduce a parasitic capacity due to the metal film of a substrate and to extend the width of a frequency band by providing wiring regions formed oppositely on two substrates provided through a cavity separately from each other. CONSTITUTION:Wirings regions 12a, 12b provided on a first substrate 11 and a wiring region 17 for connecting a photoelectric element 15 to a photodetector 16 on a second substrate 18 are formed separately from each other. For example, with electrodes 13a, 13b provided on the substrate 11 as posts a cavity 29 is provided between the substrates 18 and 11 by a bridging structure having the substrate 18 provided with the element 15 and the photodetector 16 through the electrodes 13a, 13b and wiring regions 14, 14 as a ceiling floor face. Thus, the element 15, the photodetector 16 and the region 17 are disposed on the bridge in a hollow part. Accordingly, a parasitic capacity formed between the region 17 and a ground electrode can be reduced. Thus, when an optical receiver is composed, a resonance frequency can be set to 10GHz or more, and the width of its frequency band can be shifted to a high frequency range.

Title: Light output stabilizer for semiconductor laser
Inventor: YASUDA HIROAKI
IPC: H01S5/068
Filed: 1991-11-18
Abstract: PURPOSE:To stabilize the light output of a semiconductor laser by making both surfaces of cover glass of a light detector light diffusion faces. CONSTITUTION:Both surfaces 14f and 14g that the monitor beam 11B of the cover glass 14e of a light detector 14 passes are made light diffusion surfaces by, for example, rough processing or other method. Accordingly, the monitor beam 11B is diffused when it passes this cover glass 14e, and the interference property drops. Therefore, the monitor light 11B multiplex reflected between both surfaces 14f and 14g of the cover glass 14e and the monitor light 11b directly headed for a photodiode chip 14d without being multiplex reflected ceases to remarkably interfere with each other. Hereby, the quantity of light received by the light detector 14 does not fluctuate, and the light output of the semiconductor laser can be stabilized.

SOLUTION: A crystallization coefficient showing the volumetric ratio of the sum of contained crystal phases to the whole of a thin film is defined as follows. The crystallization coefficient of the thin film containing the crystal phases of silicon crystallite and silicon carbide crystallite is regarded as the sum of both the ratio of the peak intensity corresponding to silicon of the thin film to the crystal peak intensity of silicon powder in X-ray diffraction and the ratio of the peak intensity corresponding to silicon carbide of the thin film to the crystal peak intensity of silicon carbide powder in X-ray diffraction. A thin film 10 containing silicon carbide crystallite is formed by CVD, using as its raw-material gas the mixture of a gas containing Si and C such as silane with a doping gas such as diborane.  The strain gage factor of the thin film 10 can reach the one not smaller than 30% under the condition of its formation temperature not higher than 400 deg.C and its crystallization coefficient not smaller than 30%.
